• Task 5: Configuring the RMX for ICE dialing
To place federated calls between Domain A and Domain B in ICE environment
sub domains must be federated to the main domain or the RMX system must be
installed on a main domain.

Task 1: Ensuring SIP Signaling Domains are Allowed

When federating with another Lync Server environment that includes a
Polycom RMX system, you need to ensure that both the Lync Server edge
server domain and the SIP signaling domain are allowed on the federated
Lync Server edge server.
For example, if companyB wants to connect to calls managed by an RMX
system on companyA, companyB must add the companyA domains to its
list of allowed SIP domains in the Lync Server edge server.
Likewise if companyA wants to connect to calls managed by an RMX
system on companyB, companyB's SIP domains must be on the allowed
SIP domain list of companyA's edge server.
To federate a Lync Server edge server with another Lync Server
environment:
1 On the Lync Server edge server, navigate to the Computer
Management console. For example, right-click My Computer and
choose Manage.
2 In the console tree, expand Computer Management > Services and
Applications > Office Communications Server 2007 and right-click
Office Communications Server 2007 and then click Properties.
3
Click the Internal tab.
4
In the Internal SIP Domains support by Office Communications Servers in
your organizations: area, click Add Domain.
5
In the Add SIP Domain dialog box, add each SIP domain to be
supported in your Microsoft Lync deployment. In the box, type the
FQDN of the SIP domain, and then click Add. After adding all SIP
domains to be supported, click Next.
You need to add the following SIP domains:
— Microsoft Lync edge server with which you want to federate. For
example, LYNC.companyB.com.
— The FQDN of the of the SIP signaling domain of the RMX system
in companyB in the following format:
RMX_NAME.LYNC_EDGE_SERVER_NAME.DOMAIN.COM
